- In this video I’m going to show you how to install the thermostat properly on your jeep 3.7 v6 or 4.7 V8 yes they are identical installation procedures because they are basically the same engine with two or less cylinders
These engines contain found in the Dodge Durango (🤔 yes folks your jeep has the same engine as a Dodge lol)
Also the Chrysler Aspen ,jeep wrangler, Jeep grand Cherokee ,Jeep Comander and a Jeep Liberty
We’re also going to discuss some of the possibilities of why the engine is overheating or why you don’t have the proper amount of heat inside.
Here’s a great video for you to check out and burping out the air out of the system
• Jeep liberty heater no...
And you can also check out these great videos on my TH-cam playlist for jeeps

Thank you Clay for making this video. I have been struggling to figure out why my 2002 Grand Cherokee Limited 4.7L was overheating after installing a new thermostat and following the air bleed steps. Your section on the proper clocking of the thermostat made all the difference! Why no one else makes this clear is beyond me! Thanks, again.
You’re welcome Randall that’s probably because other people don’t look at things and figure out how they work…… and what and why they’re doing it. A lot of my videos have a little nuggets like that that people often overlook. Someday I may be famous.
I just have to say THANK YOU!
You saved me from taking apart the thermostat and the water pump. It just took an air bleed and adding fluid to the cooling system. This video was great and very helpful.
That is very awesome thank you so much for taking the time to write that message I really do appreciate it welcome to the channel were so happy to have you
hope God gives you a big hug the crazy things these damn cars put us through
He does…. He gave me the ability to make videos like this so I am very thankful
I wish you were closer so you can fix my car. My mechanic here got his ego hurt because I told him about your video. I’ve been having the same issue & I keep spending on new thermostats because I believe their not being installed properly. I believe my problem with the thermostat has caused other problems. I’ve had to replace the coolant reservoir twice. I’ve had to replace the radiator because it cracked. I’ve had to replace the water pump, etc.. Honestly my intention was not to hurt his ego. I firmly believe that if a person is humble enough they will accept that no matter how experienced they may be there’s always room for improvement, for learning something new. I like that you accepted that you messed up by not getting it. You did not allow your ego to get in the way & you even let the world know. By teaching you are growing too. Thank you for the video. God bless.🙏🏼😊🙏🏼
P.S if you know of a mobile mechanic in the San Fernando valley please let me know. 🙏🏼
Your suggestion on the drilling 1/8 holes in stat worked. I did 3, worked so well. My new thermo was in right position but the pump being able to draw liquid is so great. It did the trick in getting rid of the air lock... thank you so much!!
Thank you. That filled in some blanks from other videos I've watched. Today's project, replace my daughter's thermostat in her Jeep Liberty.
Your Awesome.... Thank you for your time to show people how to fix their own vehicles. Its greatly appreciated! Sorry you get so many whiners that have no respect for what your doing! Two of your other videos helped me diagnose and fix the problems! Thanks again!
Well thank you very much Thomas I’m sure you’re very awesome as well for making my day a little bit better with your kind words I greatly appreciate it welcome to the channel were very happy to have folks like you here
@@sharpcarco Thank you Sir!
I flushed my 2004 Jeep Grand Cherokee limited, 4.7 motor. I added the flush chemical, ran around for 3 days (As per instructions) Then I drained the radiator, filled it with distilled water, ran it for 10 minutes, drained that and did that two more times. (Three flushes total) So, on the fourth time I filled it with coolant. As I watched the burp valve (8mm set screw) it just kept steaming. Water/coolant never came out, just steam. So, I let it run and would add a tiny bit of coolant as needed. I also kept an eye on the temp gauge and noticed it climbing past the 180 mark where it usually rides, past the 210 mark, and beyond that. So Before that got out of hand, I shut it off. Now, when it runs without the radiator cap, it just spews coolant out like "Old Faithful" and nothing but steam comes from the burp valve. What is going on? I'm going to change the thermostat and see if that's it, because it's the cheapest, most straightforward test I can come up with. Any ideas?
Thanks for this video
I wish I could do this myself.. mechanics in my town are not so honest.. it’s soo hard trying to get something done.
I'll work on your engine!
Girl u can! I did a complete engine swap on my jeep last summer! By myself! Clay helped watching his videos. If I can do it right after having a baby, u can!!
You can.. you just gotta go out there to understand everything for the first time and get your hands dirty cant say u wishwith youtube
If you have trouble removing the 8mm plug ; tighten if first . For some reason pipe threads bind up and by tightening until it moves ,unbinds it then you can remove it or loosen it to blead the air out . You can do this to all pipe threads .
Or if you're going to do this project, Loosen the plug while the engine is hot the night before because the heat will usually help during expansion and contraction. I had to burp my 5.7L Hemi and even with the front end jacked up it was a slow pain in the ass process taking turns squeezing both radiator hoses before I got it burped enough.
Thank you my man helped me alot
Well thank you for taking the time to write that I greatly appreciate you as well
Thanks so much man. I subcribed
I appreciate that Jim we’re very happy to have you thanks for the kind words God bless and have a great day welcome to the channel sometimes it’s hit or miss but I always try to make it fun even though some people don’t like it…..
That’s why it’s called the Clayway!!!!
Very knowledgeable. Good job.
Glad it was helpful! I love that video it’s great for people who pay attention… so thank you and welcome to my channel
What happen to me was my Jeep 5.7 Cherokee was overheating temp so when it did that I stopped the truck and started it back up and the overheating issues would stop for about 15 min of draving. So now I was getting my powersteering pump replaced and the mechanic said u need a new battery. So I got all I needed and in stalled. So here we are and my truck is good. No overheating issues so far. But took ot for a 40 min run and so far so good. Also I put a 180 thermostat on my jeep and yes it ran cooler. But my miles per gallon went very low. So I bought a 203. And still no overheating and my miles per gallon are going up.
I wonder why your miles per gallon was so affected that’s kind of strange none of that shit had anything to do with miles per gallon I would have to suspect there’s something else going on
Not sure
I learned a lot from you
That is true you definitely need to Love your enemies and thank you so much for the compliments I greatly appreciate that welcome to the Channel ….. very happy to have you
Thank you! Legend!
Tell us more about!!!! Jk welcome
To my show !!! Happy to have folks like you here !!
inst the point of the bleeder screw on the thermostat housing , to bleed any extra air out of the coolant system? just having the gasket in the housing upside down could cause air to leak in ?
After replacing the fuel pump in my Jeep grand cherokee laredo 3.7 WK- Im now having a problem with a vapor lock and my new pump is making a ringing/humming noise off and on-is there a way to fix it with a inline check valve or inline filter of some sort. I have to release pressure on the fuel rail to re-crank it after it runs for more than 20 minutes/ which is a possible fire risk.
My Jeep Liberty running hot after replacing Thermostat and water pump but it’s not showing is getting hot in the inside and I had water coming from the small hose to the radiator to the reservoir bucket
Would the thermostat being stuck cause the temp. to come up fast but stop at normal. I had it blow the upper hose off then I found the end was broken off the neck that would stop the hose clamp.
Hi bro thanks for weaching Vdio ?
I have a 03 jeep Liberty sport 3.7 v6 overheating I have replaced the thermostat properly, the coolant hoses, water pump, radiator and electric fan no signs of a failed head gasket present any advice I am a mechanic by trade and running out of ideas
Excellent Video Sr!!!. I just replaced my new thermostat and I still have same problem with the overheating.. I found this video and now I would like to ask if I can removed the new thermostat and rotare into the correct position like how you show in this part min 7:15 or need to order a new thermostat?
Did you find our your issue? Mines doing the same ! 😢
Who was that masked man😂😂😂
I have a Jeep Liberty 3.7. Bought it off some dummy who didn't tell me it had an overheating issue. It idles forever just fine, I can drive it maybe 8 - 10 miles then it starts overheating past the mid point on the gauge and will keep going until boiling over. Replaced water pump, thermostat, temp sensor, havent changed radiator yet. No head gasket symptoms that I can see.
Yeah that’s the terrible thing about these blocks is they have small hairline cracks in them sometimes and they don’t show the indications of a head gasket but I do recommend the procedure that I tell you at the end of the video when I talk about drilling some holes in the thermostat I have seen them get another six months or a year out of them after doing that it allows the pressure not to build up on the inside of the engine the same way
@@sharpcarco it's just odd I can drive it for 10 miles maybe before it starts overheating. Honestly I haven't pursued the issue further because it's fine for my work commute and most local runs. Im gonna maybe swap out the radiator at some point just haven't been bothered yet. I had a Dodge Neon did the same thing. Could drive it for maybe 15 miles or so before it started getting hot.
Hi Clay, thanks for the video. I am preparing to change my thermostat. The problem with mine is that it is fine until im driving on the freeway. Going past about 60 mph the temperature will rise at a decent pace to too hot. If I pull over and idle the engine, it cools down right away. Im pretty sure it might be the thermos getting stuck, but if this doesn’t resolve my issue what would you think?
That’s an interesting problem.
I would have to guess possible airflow through your radiator could be a potential reason for that…
Is your air-conditioning running during this problem?
Is the temperature extremely high outside in your area?
These are just some of the thoughts that I have I would recommend taking it to one of the self cleaners if you don’t have a power washer at home and trying to blow out the dirt between the radiator and the condenser.
Then we’re just some thoughts off the top of my head
Thank you so much for the kind words were very happy to have you welcome to the community
Where you able to resolve the problem on your jeep?
@@craniaxleon6277 Yes it was the thermostat, I don't think it had to be replaced, maybe just reinstalled. The part is really cheap so I just got a new one in case.
I think if you drill holes in the thermostat will be more coolant flow that could be bad for the system cause the antifreeze will take more time cool down and the fan will be working overtime and antifreeze will be burned out more quickly.
I do believe I covered that pretty well it was definitely the very last thing I said as a very last resort. If you were having to do that because you’re having an overheating problem more than likely you’re getting combustion gases inside the cooling system…
@@sharpcarco I got another issues besides the overheating in my 2004 jeep liberty 3.7L is I have to invent a cabin filter cause the humidity is getting in my ac system and my evaporator is getting corrosion.
Well that’s common that’s called electroless is it happens on aluminum products that’s just a problem overtime. And how your air conditioning system works it literally sucks the humidity out of the atmosphere inside the cabin. And that humidity is then collected on the condenser itself. Technically speaking it’s designed to do that
Dear Clay, thanks for your video. I just had the thermostat changed, but now both hoses get extrmely hot and hard and my Jeep is not running smooth. So, I will let somebody double check if the thermostat is installed correctly. Hot air still not working in the car. System wasn't burped. I hope that those 2 issues will solve the problem. Indicator on the dashboard is "stable". If you have any other idea on what the problem could be, please let me know? Don't want to loose my Liberty 2003!! Greetings from Sint Maarten!
Did you try what I mentioned at the end of the video drilling the holes in the thermostat?
@@sharpcarco No, not yet, will check if it's installed correctly and burp the system first. But the 2 hoses being very hot and hard indicates a problem with the thermostat? Or something else I should take in to consideration?
@@wilsonpercussiedid you ever figure this out? Dealing with the same issue on my 06 3.7 Awd
Hi Clay, I was referred to you by Cyclone Clyde and I was looking to get work done on my 2006 Saab 93 sport combi wagon in the New York City area. He mentioned that you may know someone. Any help would be greatly appreciated. Thank you.
No I’m sorry I don’t have any contacts out that way wish I could be more help
Hi I have a jeep commander if u let it sit there couple of minutes the temperature goes half way and the fan turns on but if start driving over 35 mph the temperature goes down to quarter temp
Well it sounds like there’s air in the system to me. Try a little bit more to get it out if that doesn’t work
Pop the thermostat out drill like two or three holes in it like I talk about. Then give it a try
Ok I’ll try it out thank you
For some reason the air bleeder hole is letting out white smoke when trying to bleed the air out
It’s just hot coolant. Shouldn’t be a concern but you should’ve already had it open well before it got that hot.
Got a 2004 Jeep Grand Cherokee with the v8 4.7L , it overheats when at idle, the fan is working, it gets so loud when at idle (drive through for example you can't have a conversation) , local shop changed the thermostat a couple years ago, wondering if they might have put it in the wrong way? and or not bleed the system correctly? It runs at normal temp at highway speeds, but very quickly overheats when you come to a stop(idle), where should I start first?
Well your clutch fan is bad you must have a mechanical one on there it is not supposed to be loud when you first start the vehicle I would highly recommend replacing that.
And if you replace the thermostat like I described in the video and it still does it watch the end of the video when I start talking about drilling holes inside the thermostat which will ease some of the pressure from the inside of the Engine
@@sharpcarco
It only gets loud when it overheats, not at first startup
need some advice please changed the water pump radiator 3thermostates fan and me burp it no milky white in oil sound great runs hot after awhile slowly runs hot plz could you help on fixed my son doing all this for me can you plz give advice and we also replace the plastic thangy resovior
Well take a look towards the end of the video where I start talking about drilling holes in the thermostat for some reason these often need that and I’ve done it quite a few times and I’ve had people tell me in the comments they did it and it solve the problem even though I don’t know why you would have to do that I’m guessing it’s because of the way the heater core lines run into it that seems to make the most sense
@@sharpcarco ok my heater core is slso bad and my son enabled that i have the new heater core which says going take a while to put on but im going to send him your video tell him to watch til the rnd now i just drive it to my moms in the other side if town and back did nit run hot at all but usually i have drive alittle more before runs hot i dont let it go all the over to red before i come and park it but 2 dats ago he did that burp letting air out his ex wife came over put little water she said it may just need water but i going drive around more in little bit just cant right got to many grand kids over i got left leg cut off mid knee or i br working on car myself
My 2005 jeep 3.7 overheats but I do have heat.
Top radiator hose is hard. Radiator fans are on. The air coming out the radiator is cold
If I’m understanding your message correctly it definitely sounds like you have a blown head gasket.
I would recommend a combustion gas detection leak test.
@@sharpcarco @Kevin Byrne @Pine Hollow Auto Diagnostics I do have heat inside the car...
after posting my comments. I did reach down and the lower radiator hose was cold.
I squeezed the lower hose in a couple of different places. Its pretty short. Is there a spring inside the hose to keep it from collapsing just before the radiator? I felt something hard in there .
If the thermostat is stuck closed. Why was I getting heat inside the car? I would use the heater to bring down the temp.
Thanks....
Tim you’re probably just low on coolant.
If you’re able to bring the temperature down by turning on the heater when The engine is cold before you start it up in the morning time I had some coolant to it
I changed the thermostat and fans kick on and its not leaking around the water pump and mine over heats random idk what the deal is
That’s strange. I don’t believe I’ve experienced random overheating but there has to be something causing it.
Only does it sometimes when its just sitting
What about normal temp while idling but overheats while driving.
Hey Joe sorry to hear about that brother would have to assume that you have a bad head gasket….. you could try some fiber lock head gasket repair in there if it’s only overheating above an idle that might be help. Do the procedure exactly how the instructions say.
what causes these engines to overheat while sitting in the drive through? not get so hot I have to shut it off just gets to the "3/4" mark if you will.
Usually poor flow. If you watch the video, I do explain how you can potentially take care of that problem.
You didnt mention the coolant temperature sensor or the ECT sending unit.
Why would I do that? There’s no such thing as a ECT sending unit on this vehicle.
The temperature sensor is a potentiometer style switch it regulates voltage sent to the Ecm which interprets the voltage into the temperature of the engine it’s a very simple circuit really nothing to mention about it
? I got a 2007 jeep grand Cherokee and I just changed the thermostat and jeep tan great even lower temp than it did befire.but I'm I'm overheating my fan is electric and it has a like ceramic sensor I believe in between th harness and fan.what on earth is it called so I can look up getting one? Thanx
That is a resistor. Very rarely do they go bad.
@@sharpcarco mine crumbled into pieces in my hand
@@sharpcarco also thanx for the info!
No problem
The best place to get one of them is going to be a pick your own part junkyard general you can’t get the connectors to come apart because they pull so much amperage so I would recommend cutting it and splicing it in hopefully that’s helpful
Our jeep has both the electric fan and clutch fan, very odd
Hi Clay, Great Video, thanks! I just pulled my thermostat on my 2003 Liberty, and yes the vent was down near the bottom, but it was notched correctly in the housing.... Any thoughts??
Hi Clay, answered my own question. The friendly neighborhood mechanic who put it in, put it in backwards, aka spring side to the hose, which also puts the vent on the bottom. He then went on to tell us, since that didn't fix it, it was a head gasket, which thank goodness it's not.
Keep up the good work! Pete
Thank you thank you so much Pete You keep paying attention to things like that and you’ll be just fine God bless brother have a great day
@@sharpcarco My 2005 jeep 3.7 overheats but I do have heat.
Top radiator hose is hard. Radiator fans are on. The air coming out the radiator is cold
@@petebethke1738 then right position of thermostat is spring pointed to engine ?
@@hvillalobos1317yes. And hole up
I have a 2005 Jeep liberty and it has two fans. It only overheats when I run the AC. What could the problem be?
Well the first thing that I would check in that situation is your radiator take your vehicle to one of the self-serve car washes and use the high pressure wash to blow out the radiator and the condenser more than likely you got dust and dirt buildup in between them and it’s not allowing your engine to cool properly.
Make sure both of your fans are coming on when your air conditioner is turned on…..
@@sharpcarco radiator and thermostat are good
@@sharpcarco changed fan clutch also. Pressure checked the cooling system
I’m not saying the radiator is bad I’m saying that there is debris and dirt stuck between the fins of the radiator. Unless you removed it it’s a good possibility that it plugged but then again I’m not there so I can’t say for certain
@@sharpcarco front of radiator clean. Any info on the 2 fans? It’s the 2005 Diesel Jeep liberty

My vicahel more Overheating quickly what happen problems this ????Writing me Answor !
Really sorry can’t tell you for certain why yours is overheating very quickly it’s possible that you have a bad head gasket if it’s overheating very fast that means that combustion more than likely is going inside your cooling system and causing it to overheat quickly.
Please help me
What u need honey?
As with most of these videos you failed to show which way the thermostat sat in the housing.🤷🏽
No I didn’t you skipped past it …. I build thing like that in my videos just for people like you …. Your welcome

I’m not wearing a mask because of Covid 😂😂😂 Well I guess technically I am wearing it because of Covid my dog ate my false teeth during Covid and I couldn’t get new ones now I’m just used to not having them and also I can’t afford them…… So that’s why I was wearing it back then
@@sharpcarco It's none of his business anyway.
I can agree with that. People bust my balls for it all the time. I just always thought the real reason I was wearing the mask in the videos was actually hilarious because it is the truth.
